These are colors made not with pigments, but with nanometer-scale structures that play tricks with light, intensifying some wavelengths and diminishing others. Coming up with a way to make Vantablack, a structural color that absorbs 99.6% of the light hitting it, was a feat of engineering:To put this in perspective, if you think of a forest of trees about a metre in diameter, then these trees would scale to be around one kilometre high. Light falling on this very tall forest of tubes bounces around and is almost perfectly absorbed.The article on cutting-edge attempts to create new colors with structure includes photographs and descriptions of very diverse animals that use this technique:Butterflies, that create iridescent colors on their scales. (see 6/15/10)A snake that has some of the blackest scales found in nature.Sardines with silvery sides.Live Science shares another secret: “Butterfly Wing Optics Help to Cheaply Create Bright, Realistic Holograms.” The blurry holograms seen at concerts, in movies and on credit cards could much more colorful and clear, David Roos reports, by mimicking the nanostructures on butterfly wing scales.We know from previous reports on structural colors or “photonic crystals” that birds, spiders, beetles and mammals also use them (6/05/08). These diverse animals could not have gotten their secrets by descent from a common ancestor because many intermediate animals in the evolutionary scheme do not have them. The only other way for evolution to handle this would be for the common ancestor to have the secret, but most animals down the line lost it. That would also create a challenge: how did the common ancestor come up with a trick like that? There’s only one cause that we know of that can share technology across multiple, independent platforms. That cause is – you guessed it – intelligent design.
28 June 2012 A South African-led research team working on Australopithecus sediba, the 2-million-year-old human ancestor recently discovered in South Africa, have published new findings on what our early ancestors ate that are causing a stir in scientific circles. It’s clear that these hominins didn’t brush their teeth on the morning nearly two-million years ago when they fell into a sinkhole not far from present-day Johannesburg. Remains of their meal have been found in plaque in their teeth. The 1.9-million year old Australopithecus sediba, found in South Africa’s Cradle of Humankind by professor Lee Berger of Wits University in 2008, reveal that these hominins ate parts of trees, shrubs or herbs. Berger, Reader in Human Evolution and the Public Understanding of Science at the Institute for Human Evolution at Wits, led the team, comprising nine leading scientists from across the globe, that published the latest findings on Australopithecus sediba.A (very) long-overdue trip to the dentist … While examining the teeth of the two individuals so far excavated, Berger noticed stains or plaque on the teeth – tartar or calculus, a mineralised material that forms on teeth. “In this plaque, the scientists found phytoliths, bodies of silica from plants eaten almost two-million years ago by these early hominins,” the research team said in a statement this week. The well-preserved teeth were analysed in different ways. Dental micro-wear analyses of the tooth surfaces and high-resolution isotope studies of the tooth enamel were conducted. “We have a very unusual type of preservation in this instance as the state of the teeth was pristine,” said Peter Ungar, distinguished professor of anthropology at the University of Arkansas and the scientist responsible for conducting the dental micro-wear studies of the teeth. Multi-disciplinary research team The research was published in the online edition of the prestigious journal Nature on Wednesday, and will appear in the 5 July print edition. The main author is Amanda Henry of the Max Planck Institute for Evolutionary Anthropology in Germany, a specialist in dental calculus and tartar. Other specialists on the multi-disciplinary team included dental micro-wear specialists, isotopic specialists and phytolith researchers – scientists who study the physical remains of ancient plants. “We have been very lucky to bring together such a diverse group of talented individuals to conduct this study,” said Henry. Using the isotope analysis, the dental micro-wear analysis and the phytolith analysis, the researchers “closed in on the diet of these two individuals, and what they found differs from other early human ancestors from that period. “The micro-wear on the teeth showed more pits and complexity than most other australopiths before it. The phytoliths gave an even clearer picture of what the animals were consuming, including bark, leaves, sedges, grasses, fruit and palm,” the statement reads. Animal that took advantage of forest resources Tests were conducted on the surrounding sediments in the area, to ensure the samples from the plaque were really part of the diet, and not contamination from elsewhere. “By testing the sediments in which the hominid was buried we can be sure that the phytoliths in the calculus were not from post-depositional contamination,” said professor Marion Bamford from the Bernard Price Institute for Palaeontology at Wits, who worked on the phytolith analysis. “These findings tell us a really nice story about these two individuals. We get a sense of an animal that looked like it was taking advantage of forest resources,” adds Ungar. “This kind of food consumption differs from what has been seen in evidence from other australopiths. They come out looking like giraffes in terms of their tooth chemistry. A lot of the other creatures there were not eating such forest resources.” The finding has been creating great excitement in the scientific world. Bark … not expected “The find is unprecedented in the human record outside of fossils just a few thousand years old. It is the first truly direct evidence of what our early ancestors put in their mouths and chewed – what they ate,” said Berger. “I found the evidence for bark consumption the most surprising,” said Berger. “While primatologists have known for years that primates, including apes, eat bark as a fallback food in times of need, I really had not thought of it as a dietary item on the menu of an early human ancestor.” Matt Sponheimer, a Professor at the University of Colorado, Boulder, who worked on the isotopic research, explains: “The results suggested a different diet than we have found in other early hominins, and were rather like what we find in living chimpanzees. We were not expecting Sediba to look unlike Australopithecus and Homo as various researchers have suggested affinities to one genus or the other, or both.”New hominin species In 2010, Berger and his colleagues unveiled the 2008 find, an entirely new hominin species. In September 2011, the almost complete hand skeleton of sediba was unveiled, together with the brain, hip, foot and ankle. Five papers detailing the findings and analysis of the discovery were published in the prestigious journal Science. The very evolved hand with a long thumb, like a human, with long arms like an ape, indicate that sediba was bipedal but also able to climb. The hand also suggests that sediba was capable of tool manufacture and use. The advanced pelvis and long legs suggest it was able to stride and possibly even run like a human. Sediba has been described as a “transitional species” between Australopithecus africanus and either Homo habilis or Homo erectus. Other animal fossils have been found with the sediba bones – sabre-toothed cats, hyenas, antelopes, mice, birds and snails. Sediba is a Sotho word for a well or a spring; the species was so named because it was hoped that “a great source of information will spring from the fossils”. Source: City of Johannesburg
2 May 2013South Africa’s democracy would not be sustainable or successful if the plight of the working class, employed and unemployed, was not sufficiently attended to, President Jacob Zuma said on Wednesday.Speaking at the main Congress of SA Trade Unions (Cosatu) Workers’ Day rally in Kimberly, Northern Cape, Zuma said that the African National Congress (ANC) had a strong bias towards the working class and poor.“The ANC bias towards the working class does not mean we have abdicated our responsibility as a liberation movement to mobilize the broadest strata of society for fundamental transformation.“It simply means we have correctly understood that our democracy will not be stable, sustainable and successful if the plight of the working class, employed or unemployed, is not sufficiently attended to,” Zuma said.Workers’ rights such as the right to fair labour practices and the right to form and join trade unions were enshrined in the Constitution. “These are very important rights which must not be taken for granted.”Zuma said a tendency to divide workers or undermine collective bargaining among others should be guarded against.“Unity within Cosatu is paramount. We need a united Cosatu that is able to devote its attention to promoting the rights of workers. Thus we urge the labour movement to work seriously at uniting the federation and to resolve whatever differences there may exist.”Workers were the creators of the country’s wealth and they had to get an equitable share in the wealth, Zuma said, adding that attention needed to be paid to the plight of mineworkers and farm workers.“As we focus on miners and farm workers, we also remember those workers who tragically lost their lives in Marikana in the North West and related violent incidents. We have to draw lessons from Marikana.”The National Development Plan (NDP) was the country’s socio-development blueprint for the next 20 years, Zuma said.“We reiterate that those who have views about the NDP should feel free to raise them in the spirit of the democratic culture within the movement … Views cannot be suppressed. However, work is continuing to implement the NDP.”At government level, the Department of Performance Monitoring and Evaluation has already begun developing a draft medium-term strategic framework for 2014-2019, as the first five-year building block of the NDP.The intention is to submit the first draft of the 2014-2019 NDP-aligned framework to the 2013 July Cabinet lekgotla. This can then be refined so that it can be submitted to the new Cabinet for approval as soon as possible after the 2014 elections.This will enable departments to include the new targets in their individual five-year strategic plans, which they will be starting to work on later this year and in early 2014.Source: SAnews.gov.za

CALGARY – Health Canada has approved a safe injection site for opioid drugs in Calgary.Alberta Health says a temporary site will open soon in the parking area of the Sheldon M. Chumir Health Centre while a permanent site inside the centre is being constructed.Alberta Health says patients will also be able to get treatment, including suboxone, methadone, and counselling.Evidence shows that supervised consumption services save lives, reduce transmission of infections by providing sterile needles and equipment and build safer communities by reducing public substance use and discarded needles.Last week, Health Canada approved four safe injection sites for Edmonton and one for Lethbridge, and those are expected to open later this year or early next year.Jessica Holtsbaum of the group Changing the Face of Addiction, called it great news.“It will save lives and provide those with substance-use disorders an access point to further treatment. It is a long overdue step in the right direction. However, this is only one small step and momentum can’t end here.”The province is providing $2.2 million for startup costs and for construction of the temporary and permanent locations at the Chumir health centre. The province will also provide operational funding for all six supervised consumption sites approved for Alberta.As of mid-August 2017, 315 people have died of apparent fentanyl-related overdoses in Alberta. There were 586 suspected opioid-related deaths in the province last year.The Canadian Institute for Health Information has said data from Alberta suggests emergency room visits related to heroin and synthetic opioid overdoses spiked almost 10-fold in the last five years.The first safe consumption sites in Canada were set up in Vancouver. Health Canada has approved other sites in Montreal and Toronto.Last month, Dr. Theresa Tam, Canada’s chief public health officer, said at least 2,816 Canadians died from opioid-related causes in 2016 and that number is expected to grow this year.

SASKATOON – Fertilizer giant Nutrien Ltd. (TSX:NTR) says it plans to sell all of its holdings in Israel Chemicals Ltd. in a secondary share offering for an expected US$700 million.The sale comes as one of the requirements set out by global regulators for Potash Corp. and Agrium Inc. to merge to become Nutrien.Nutrien also needs to sell its shareholdings in Arab Potash Co. and Chile-based SQM within 18 months, and had to sell off some U.S. operations and convert its holdings in China-based Sinofert Holdings Ltd. to a passive investment before it closed the merger.The company secured U.S. approval for the deal in late December to clear the way for the company to start trading on Jan. 2 as Nutrien, since approvals from Canada, India, China, Brazil and Russia were already in place.The combined company, which has fertilizer mining operations in Canada and the U.S. as well as more than 1,500 farm retail centres globally, proposed the merger as a way to expand its combined reach and achieve $500 million a year in cost savings.Nutrien, now with about a $43-billion market capitalization, is headquartered in Saskatoon with corporate offices in Calgary.
